This paper aims to analyze the impact of conjectural “too-big-to-fail” (TBTF) guarantees on big and small US financial institutions’ stock prices during the 2008-2009 banking crisis.
The paper analyzes shocks to stock market investors’ expectations of government aid to banks in distress and respective spillover effects using an event study approach. We focus on three major events in late 2008, namely, the Lehman bankruptcy, the Citigroup bailout and the first announcement of the Capital Purchase Program (CPP) by the US Government.
The authors found significant differences in market reactions to the respective events between small and large banks. For both the Lehman and the CPP event, abnormal returns on big banks’ stocks are negative, while small banks’ stocks tend to generate positive abnormal returns. In contrast, large banks strongly outperform small banks in the case of the Citigroup bailout. Results for a control group of non-financial firms indicate that this behavior may be specific to the banking industry. The authors observed significant spillover effects to both competitors and non-competitors of Lehman and Citigroup, and concluded that while the Lehman event shook the widely held belief in an implicit TBTF subsidy to large banks, the TBTF doctrine was reinstated shortly thereafter.
This paper shows that conjectural TBTF guarantees are priced in by equity investors. While government aid to large banks in distress may prevent negative effects on the stability of the financial system, it may also create negative externalities by putting small banks at a competitive disadvantage. The findings suggest that US and European regulators’ recent policy measures directed at establishing reliable bank resolution schemes should be a step in the right direction to level the playing field for small and large financial institutions.
